この発明は回動制御装置を備えた塩水噴霧試験機に係り、特に塩水噴霧試験機によって腐食促進試験を実施する際に、試験結果にムラを生じさせることのない回動制御装置を備えた塩水噴霧試験機に関するものである。   The present invention relates to a salt spray tester equipped with a rotation control device, and in particular, salt water provided with a rotation control device that does not cause unevenness in test results when a corrosion acceleration test is performed by the salt spray tester. It relates to a spray tester.

金属材料又はめっき、無機被膜若しくは有機被膜を施した金属材料においては、この金属材料の表面処理された部分の防錆・防食効果を調べるために腐食促進試験(「耐食性試験」とも換言できる。)が行われる。

ところで、従来の塩水噴霧試験機においては、試験槽内に試料を載置する際に、固定式の試料載置枠体を使用していた。
このとき、塩水を噴霧する噴霧手段は、前記試験槽の中央部位に設けられていた。
この結果、前記噴霧手段によって塩水の噴霧を行い、腐食促進試験を実施した際には、前記噴霧手段と前記試験槽内の左右部位や前後部位に載置される試料との間の距離にバラツキが生じ、正確な腐食促進試験を実施することができないという不具合があった。
By the way, in a conventional salt spray tester, a fixed sample mounting frame is used when mounting a sample in a test tank.
At this time, the spraying means for spraying the salt water was provided at the central portion of the test tank.
As a result, when salt water is sprayed by the spraying means and a corrosion acceleration test is performed, the distance between the spraying means and the samples placed on the left and right parts and the front and rear parts in the test tank varies. As a result, there was a problem that an accurate corrosion acceleration test could not be performed.

このような不具合を解消するために、出願人は、上記の特許文献1に開示される腐食試験機を開発した。
しかし、この特許文献1に開示される腐食試験機においては、以下のような不都合があり、改善が望まれていた。
(1)試料載置枠体を一方向にのみ回転可能とした。
この結果、腐食促進試験を実施した際に、試料の回転方向の前側に位置する部位の腐食量が試料の回転方向の後側に位置する部位の腐食量に比べて大きく、試験結果にムラが出てしまう。
(2)また、試料載置枠体を連続回転させた。
この結果、腐食促進試験を実施した際には、試料の回転方向の前側に位置する部位であっても、回転方向に対する試料の傾斜状態、つまり、回転方向に対して傾斜が少ない部分の腐食量が回転方向に対して傾斜が多い部分の腐食量に比べて大きく、試料の回転方向の前側に位置する部位においても試験結果にムラが出てしまい、正確な腐食促進試験を実施することができない。
In order to solve such a problem, the applicant has developed a corrosion tester disclosed in Patent Document 1 described above.
However, the corrosion tester disclosed in Patent Document 1 has the following disadvantages and has been desired to be improved.
(1) The sample mounting frame can be rotated only in one direction.
As a result, when the corrosion promotion test is performed, the corrosion amount of the part located on the front side of the sample rotation direction is larger than the corrosion amount of the part located on the rear side of the sample rotation direction, and the test results are uneven. It will come out.
(2) Moreover, the sample mounting frame was continuously rotated.
As a result, when the corrosion acceleration test is performed, the amount of corrosion in the portion of the sample tilted with respect to the rotation direction, that is, the portion with a small inclination with respect to the rotation direction, even at the front part in the sample rotation direction. Is larger than the amount of corrosion in the part with a large inclination with respect to the rotation direction, and the test result is uneven even in the part located on the front side in the rotation direction of the sample, and an accurate corrosion acceleration test cannot be performed. .

この発明の目的は、試験結果にムラを生じさせることなく、正確な腐食促進試験を実施し得る塩水噴霧試験機の回動制御装置を実現することにある。   An object of the present invention is to realize a rotation control device of a salt spray tester capable of performing an accurate corrosion acceleration test without causing unevenness in test results.

そこで、この発明は、上述不都合を除去するために、本体部と、この本体部の上部を覆う蓋部と、前記本体部と蓋部内に形成した試験槽と、試料を載置するためにこの試験槽内に形成した試料載置枠体と、前記試験槽内に塩水を噴霧する噴霧手段とを備え、前記試験槽内を所定の温度状態に維持しつつ塩水の噴霧を行い、試料の防錆・防食効果を調べるための腐食促進試験を行う塩水噴霧試験機において、前記試料載置枠体を回動させる回動手段を設け、この回動手段を制御して前記試料載置枠体を回動させる制御手段を設け、この制御手段は、前記試料載置枠体を所定の時間毎に所定角度だけ一方向に回転させる一方、所定の回転角度に達した後には、前記試料載置枠体を所定の時間毎に所定角度だけ他方向に回転させ、所定の回転角度に達した後に試験を終了させるべく制御することを特徴とする。   Therefore, in order to eliminate the above-mentioned inconvenience, the present invention provides a main body, a lid that covers the upper portion of the main body, a test tank formed in the main body and the lid, and a sample tank for placing a sample. A sample mounting frame formed in the test tank and spray means for spraying salt water in the test tank are provided, and salt water is sprayed while maintaining the inside of the test tank at a predetermined temperature state, thereby preventing the sample. In a salt spray tester for performing a corrosion acceleration test for investigating the rust / corrosion prevention effect, a rotation means for rotating the sample mounting frame is provided, and the sample mounting frame is controlled by controlling the rotation means. Control means for rotating is provided, and the control means rotates the sample mounting frame in one direction by a predetermined angle every predetermined time, and after reaching the predetermined rotation angle, the sample mounting frame Rotate the body in the other direction by a predetermined angle every predetermined time, And controlling so as to terminate the tested later.

以上詳細に説明した如くこの本発明によれば、本体部と、本体部の上部を覆う蓋部と、本体部と蓋部内に形成した試験槽と、試料を載置するためにこの試験槽内に形成した試料載置枠体と、試験槽内に塩水を噴霧する噴霧手段とを備え、試験槽内を所定の温度状態に維持しつつ塩水の噴霧を行い、試料の防錆・防食効果を調べるための腐食促進試験を行う塩水噴霧試験機において、試料載置枠体を回動させる回動手段を設け、回動手段を制御して試料載置枠体を回動させる制御手段を設け、制御手段は、試料載置枠体を所定の時間毎に所定角度だけ一方向に回転させる一方、所定の回転角度に達した後には、試料載置枠体を所定の時間毎に所定角度だけ他方向に回転させ、所定の回転角度に達した後に試験を終了させるべく制御する。
従って、噴霧手段によって噴霧される塩水を静止状態で受けることができる一方、所定の時間毎に所定角度だけ一方向、そして他方向に試料載置枠体が回転されることによって、試験槽内を試料が移動することとなり、試験結果にムラを生じさせることなく、正確な腐食促進試験を実施し得る。
また、試料載置枠体が所定の時間毎に所定角度だけ一方向、そして他方向に回転されることにより、試験槽中に充満する前記噴霧手段によって噴霧される塩水に晒される(「暴される」とも記載できる。)のを均一化することができ、より一層試験結果のムラの発生防止に寄与し得るものである。

詳細には、例えば、前記試料載置枠体6を間欠的に回動させる時間である所定の時間を30分間とする。
また、前記試料載置枠体6を間欠的に回動させる角度である所定角度を90度とする。
更に、所定の回転角度を360度の1回転とする。
そして、前記制御手段21によって前記試料載置枠体6を30分毎に90度だけ一方向に回転させて1回転させた後に、前記試料載置枠体6を30分毎に90度だけ他方向に回転させて1回転させるように制御する。

また、所定角度の場合には、90度として360度を4分割する設定としたが、2分割以上とすることが可能である。
更に、前記制御手段21によって前記試料載置枠体6を回動させる際にも、正回転1回と逆回転1回とを1サイクルとし、この1サイクルの終了によって腐食促進試験が終了する旨の説明としたが、正回転や逆回転の回転数を任意に設定することが可能であるとともに、1サイクル以上のサイクル数を設定することによって腐食促進試験の終了時とすることも可能である。
Further, the control means 21 has a timer 31 for measuring a predetermined time, and controls the sample mounting frame 6 to rotate intermittently, that is, to perform forward rotation and reverse rotation, respectively.

In addition, a predetermined angle that is an angle by which the sample mounting frame 6 is intermittently rotated is set to 90 degrees.
Further, the predetermined rotation angle is set to one rotation of 360 degrees.
Then, after the sample mounting frame 6 is rotated in one direction by 90 degrees every 30 minutes by the control means 21 and rotated once, the sample mounting frame 6 is moved by 90 degrees every 30 minutes. It is controlled to rotate in the direction to make one rotation.
At this time, the rotation speed for rotating the sample mounting frame 6 is such that the salt mist from the spray tower 14 is uniform over the entire surface of the sample mounting frame 6 (for example, 1.4 ml / h ± 0.1 ml / h). For example, 1/3 rpm.
The setting of the predetermined time and the predetermined angle can be variously changed in consideration of the performance of the salt spray tester 1, the content of the corrosion acceleration test, the state of the sample 5, and the like.
That is, in the case of a predetermined time, it is possible to set from a short setting of about 1 minute to a long setting exceeding 1 hour.
Further, in the case of a predetermined angle, the setting is made such that 90 degrees is divided into 360 degrees, but it can be divided into two or more.
Further, when the sample mounting frame 6 is rotated by the control means 21, one forward rotation and one reverse rotation are defined as one cycle, and the corrosion acceleration test is completed at the end of this one cycle. However, it is possible to arbitrarily set the number of forward and reverse rotations, and to set the number of cycles of one cycle or more to the end of the corrosion promotion test. .

追記すれば、準備工程101としては、試料5を前記試料載置枠体6に載置してセットする作業や、塩水、供給圧縮空気の状態を確認して最適な塩霧状態に準備する作業などが考えられる。
また、第1制御工程102は、前記試料載置枠体6を一方向に回転、つまり正回転させる工程である。
更に、第2制御工程103は、前記試料載置枠体6を他方向に回転、つまり逆回転させる工程である。
When the corrosion promotion test is performed by the rotation control device 29 of the salt spray test machine 1, for example, the preparation process 101, the first control process 102, and the second control process 103 are performed, and the test ends 104. It is.

前記第2制御工程103が終了した後には、試験終了104となり、前記塩水噴霧試験機1の回動制御装置29による腐食促進試験を終了させる。   After the second control step 103 is finished, the test is finished 104, and the corrosion acceleration test by the rotation control device 29 of the salt spray tester 1 is finished.

これにより、本体部2と、この本体部2の上部を覆う蓋部3と、前記本体部2と蓋部3内に形成した試験槽4と、試料5を載置するためにこの試験槽4内に形成した試料載置枠体6と、前記試験槽4内に塩水を噴霧する噴霧手段7とを備え、前記試験槽4内を所定の温度状態に維持しつつ塩水の噴霧を行い、試料5の防錆・防食効果を調べるための腐食促進試験を行う塩水噴霧試験機1において、前記試料載置枠体6を回動させる回動手段20を設け、この回動手段20を制御して前記試料載置枠体6を回動させる制御手段21を設け、この制御手段21は、前記試料載置枠体6を所定の時間毎に所定角度だけ一方向に回転させる一方、所定の回転角度に達した後には、前記試料載置枠体6を所定の時間毎に所定角度だけ他方向に回転させ、所定の回転角度に達した後に試験を終了させるべく制御する。
従って、噴霧手段7.によって噴霧される塩水を静止状態で受cけることができる一方、所定の時間毎に所定角度だけ一方向、そして他方向に試料載置枠体6が回転されることによって、試験槽4内を試料が移動することとなり、噴霧塔14と各試料5との位置関係を平均化して均等とすることができ、試験結果にムラを生じさせることなく、正確な腐食促進試験を実施し得る。
また、試料載置枠体6が所定の時間毎に所定角度だけ一方向、そして他方向に回転されることにより、試験槽4中に充満する前記噴霧手段7によって噴霧される塩水に暴されるのを均一化することができ、より一層試験結果のムラの発生防止に寄与し得るものである。
Thus, the main body 2, the lid 3 covering the upper portion of the main body 2, the test tank 4 formed in the main body 2 and the lid 3, and the test tank 4 for placing the sample 5. A sample mounting frame 6 formed inside, and a spray means 7 for spraying salt water into the test tank 4, and spraying salt water while maintaining the inside of the test tank 4 at a predetermined temperature state. In the salt spray tester 1 for performing a corrosion acceleration test for examining the anti-corrosion / corrosion effect of 5, a rotating means 20 for rotating the sample mounting frame 6 is provided, and the rotating means 20 is controlled. A control means 21 for rotating the sample mounting frame 6 is provided, and the control means 21 rotates the sample mounting frame 6 in one direction by a predetermined angle every predetermined time, while a predetermined rotation angle. , The sample mounting frame 6 is rotated in the other direction by a predetermined angle every predetermined time, Control in order to terminate the test after reaching the rotational angle of the constant.
Therefore, the spraying means 7. Can be received in a stationary state, while the sample mounting frame 6 is rotated in one direction by a predetermined angle every predetermined time and in the other direction. The sample is moved, the positional relationship between the spray tower 14 and each sample 5 can be averaged and made uniform, and an accurate corrosion acceleration test can be performed without causing unevenness in the test result.
Further, the sample mounting frame 6 is rotated by a predetermined angle every predetermined time in one direction and in the other direction, thereby being exposed to the salt water sprayed by the spraying means 7 filling the test tank 4. This can contribute to the prevention of unevenness in test results.

また、前記制御手段21は、所定の時間を計測するタイマ31を有し、所定の時間を30分間、所定角度を90度とするとともに、所定の回転角度を360度の1回転とし、前記試料載置枠体を30分毎に90度だけ一方向に回転させて1回転させた後に、前記試料載置枠体を30分毎に90度だけ他方向に回転させて1回転させるように制御する。
従って、タイマ31を有する前記制御手段21によって、腐食促進試験を行う際には、例えば、30分毎に90度だけ一方向に前記試料載置枠体6を回転させて1回転させた後に、30分毎に90度だけ他方向に前記試料載置枠体6を回転させて1回転させるように正確に制御することができ、試験結果にムラを生じさせることなく、正確な腐食促進試験を実施し得るものである。
The control means 21 has a timer 31 for measuring a predetermined time, the predetermined time is 30 minutes, the predetermined angle is 90 degrees, the predetermined rotation angle is one rotation of 360 degrees, and the sample After the mounting frame is rotated by 90 degrees in one direction every 30 minutes and rotated once, the sample mounting frame is rotated by 90 degrees in other directions every 30 minutes and rotated once. To do.
Therefore, when performing the corrosion promotion test by the control means 21 having the timer 31, for example, after rotating the sample mounting frame 6 in one direction by 90 degrees every 30 minutes, The sample mounting frame 6 can be rotated in the other direction by 90 degrees every 30 minutes and can be accurately controlled to rotate once, and an accurate corrosion acceleration test can be performed without causing unevenness in the test results. It can be implemented.

更に、前記塩水噴霧試験機1の蓋部3の形状を頂角が100度(傾斜角40度)程度の円錐形状としたことにより、蓋部3の裏面に付着した水滴がこの蓋部3の裏面部分を伝って前記本体部2の内周面部位から試験槽4内に到達することとなり、蓋部3の裏面に付着した水滴が試料5に落下するおそれが全くなく、実用上有利である。   Furthermore, the lid 3 of the salt spray tester 1 has a conical shape with an apex angle of about 100 degrees (tilt angle 40 degrees), so that water droplets adhering to the back surface of the lid 3 It will reach the inside of the test tank 4 from the inner peripheral surface portion of the main body portion 2 through the back surface portion, and there is no possibility that water droplets adhering to the back surface of the lid portion 3 will fall on the sample 5, which is practically advantageous. .

なお、この発明は上述実施例に限定されるものではなく、種々の応用改変が可能である。   The present invention is not limited to the above-described embodiments, and various application modifications are possible.

例えば、この発明の実施例においては、前記試料載置枠体を間欠的に回動させる時間である所定の時間を30分間とするとともに、前記試料載置枠体を間欠的に回動させる角度である所定角度を90度とし、一定の時間と一定角度とを設定する構成としたが、変速設定を行う特別構成とすることも可能である。
すなわち、例えば2回の正回転と2回の逆回転とを1サイクルとし、この1サイクルが終了した後に腐食促進試験を終了させる場合には、1回目の正回転時と2回目の正回転時とにおける所定の時間と所定角度とを変更するとともに、同様に逆回転時においても変更するものである。
このとき、一例としては、1回目の正回転時の所定の時間を30分間、所定角度を90度に設定する。そして、2回目の正回転時の所定の時間を15分間、所定角度を60度に設定する。また、逆回転時の場合にも同様に設定する。
つまり、前記試料載置枠体が間欠的に回動する際の時間や角度を変更して、前記試験槽内を試料載置枠体によって撹拌し、試験槽内の塩霧状態を変化させるものである。
なお、前記試料載置枠体が間欠的に回動する際の回動速度も変化させる構成を併用すれば、試験槽内の塩霧状態をより一層変化させることが可能である。
さすれば、1度の腐食促進試験において、試料に2種類以上の状態の異なる塩霧を作用させることが可能となり、均一な条件下の腐食促進試験のみでなく、複雑な条件下での腐食促進試験をも実現することが可能である。
このとき、制御手段やタイマの設定のみで対処し得ることにより、構成が複雑化するおそれが全くなく、コストを低廉に維持し得るものである。
For example, in the embodiment of the present invention, the predetermined time, which is the time for intermittently rotating the sample mounting frame, is set to 30 minutes, and the angle at which the sample mounting frame is rotated intermittently. The predetermined angle is set to 90 degrees, and a fixed time and a fixed angle are set. However, a special configuration in which a shift is set is also possible.
That is, for example, when two cycles of forward rotation and two reverse rotations are defined as one cycle and the corrosion promotion test is terminated after the completion of this one cycle, during the first forward rotation and the second forward rotation In addition, the predetermined time and the predetermined angle are changed at the time of reverse rotation as well.
At this time, as an example, the predetermined time at the first forward rotation is set to 30 minutes and the predetermined angle is set to 90 degrees. Then, the predetermined time at the second forward rotation is set to 15 minutes, and the predetermined angle is set to 60 degrees. The same setting is made for reverse rotation.
That is, the time and angle at which the sample mounting frame is rotated intermittently is changed, the inside of the test tank is stirred by the sample mounting frame, and the salt fog state in the test tank is changed. It is.
In addition, if the structure which also changes the rotational speed at the time of the said sample mounting frame rotating intermittently is used together, it is possible to further change the salt fog state in a test tank.
Then, in one corrosion acceleration test, it is possible to apply two or more different salt mists to the sample, and not only the corrosion acceleration test under uniform conditions but also the corrosion under complicated conditions. An accelerated test can also be realized.
At this time, since it can be dealt with only by setting the control means and the timer, there is no possibility that the configuration becomes complicated, and the cost can be kept low.
